       10 . The image capture device as set forth in  claim 8 , wherein the backlight unit comprises a plurality of light-emitting diodes that respectively emit light to a plurality of areas on the liquid crystal unit, 
 wherein the liquid crystal unit displays an image by transmitting the light emitted from the light-emitting diodes, and    wherein the display control unit controls an emission intensity of some of the light-emitting diodes to be relatively greater for displaying the specific area on the liquid crystal unit than for displaying the other light-emitting diodes.    
   
   
       11 . The image capture device as set forth in  claim 1 , wherein the display unit comprises a plurality of light-emitting elements to display an image, each of the light-emitting elements emitting light per pixel, and 
 wherein the display control unit controls an emission intensity of some of the light-emitting elements to be relatively greater for emitting light of pixels included in the specific area than for emitting light of pixels included in the other area.    
   
   
       12 . The image capture device as set forth in  claim 11 , wherein the light-emitting elements comprise organic electroluminescence elements.
